6 Nova Scotia Effective Load Carrying Capability Study, Energy+Environmental Economics, June 2026. Generation Resource Fuel Type Owner Capacity (MW) ELCC (%) Firm Capacity (MW) Total Steam 1590.0 - 1590.0 Combined Cycle Tufts Cove 4,5,6 Na...
AI summary The document presents a table listing various generation resources in Nova Scotia, including their fuel types, owners, capacities, Effective Load Carrying Capability (ELCC), and firm capacities. It includes data on natural gas, wind, solar, biomass, hydro, and battery energy storage systems, as well as independent power producers and wholesale market participants.
5.1.1 Interconnection Requirements IESO Nova Scotia sets performance and interconnection requirements for BESS, generation, and load connecting to the Nova Scotia transmission system. These performance and interconnection requirements will...
AI summary IESO Nova Scotia establishes interconnection requirements for BESS, generation, and load connecting to the transmission system. These requirements are being refined as technology advances and local experience grows. Inverter-based resources (IBRs) like solar and wind can be integrated, though they may require additional grid support mechanisms. The TSIR, last updated in February 2025, will be reviewed in 2026.
5.2.1 Generator and BESS Interconnection The Combined Transmission & Distribution (T&D) Advanced Stage Interconnection Request Queue[38](#page-23-1) provides the location and size of generating and BESS facilities seeking interconnection w...
AI summary The document outlines the status of generator and BESS interconnection requests in Nova Scotia, noting that 20 interconnection requests are associated with 18 projects expected to connect to the transmission system before 2030. These projects involve Transmission Provider's Interconnection Facilities (TPIF) and Network Upgrades (NU), though work related to these is not included in the report.
5.2.2 Large Load Interconnection Requests IESO Nova Scotia has received large-load requests with respect to proposed commercial and industrial projects. IESO Nova Scotia is conducting System Impact Studies for these projects based on the i...
AI summary IESO Nova Scotia is conducting System Impact Studies for large-load interconnection requests from commercial and industrial projects, based on information provided by interconnection customers about their facilities and operational profiles. Table 8 lists the locations and sizes of these facilities.
5.3.1 Western Valley Transmission System The Western Valley transmission study was initiated to identify if load growth and new generation in the area necessitate system upgrades and/or protection scheme changes. System upgrades could incl...
AI summary The Western Valley transmission study was initiated to assess if load growth and new generation in the area require system upgrades or changes to protection schemes. Upgrades may include reactive power sources, while protection changes may involve Automatic Action Schemes (AAS) or Remedial Action Schemes (RAS). The study covers 2027 and 2032 for both normal and N-1 scenarios, with 2027 results identifying necessary upgrades.
